TECHNOLOGICAL FIELD

This invention is directed to non-dairy almond based formulae for thepreparation of infant or toddler formula or other types of supplementalor functional food.

BACKGROUND

Infant formula is a manufactured food designed and marketed for feedingbabies and infants under 12 months of age, usually prepared forbottle-feeding or cup-feeding from powder (mixed with water) or liquid(with or without additional water). The U.S. Federal Food, Drug, andCosmetic Act (FFDCA) defines infant formula as “a food which purports tobe or is represented for special dietary use solely as a food forinfants by reason of its simulation of human milk or its suitability asa complete or partial substitute for human milk”.

The composition of infant formula is designed to be roughly based on ahuman mother's milk at approximately one to three months postpartum,although there are significant differences in the nutrient content ofthese products. The most commonly used infant formulas contain purifiedcow's milk whey and casein and/or skimmed milk powder as a proteinsource, a blend of vegetable oils as a fat source, lactose as acarbohydrate source, a vitamin-mineral mix, and other ingredientsdepending on the manufacturer.

A 2001 World Health Organization (WHO) report found that infant formulaprepared in accordance with applicable Codex Alimentarius standards wasa safe complementary food and a suitable breast milk substitute.

As most of the infant formulas are based on cow's milk whey and caseinas a protein source, many babies develop allergy or intolerancecondition that may be at times, life threatening.

Cow's milk allergy is a food allergy, an adverse immune reaction to oneor more of the constituents of Cow's milk (most commonly the proteinalpha S1-casein). This milk-induced allergic reaction can involveanaphylaxis, a potentially life-threatening condition.

The principal symptoms are gastrointestinal, dermatological andrespiratory. These can translate to: skin rash, hives, vomiting, andgastric distress such as diarrhea, constipation, stomach pain orflatulence. The clinical spectrum extends to diverse disorders:anaphylactic reactions, atopic dermatitis, wheeze, infantile colic,gastroesophageal reflux (GER), oesophagitis, allergic colitis, headache,oral irritation, and constipation. The symptoms may occur within a fewminutes after exposure in immediate reactions, or after hours (and insome cases after several days) in delayed reactions.

Some babies may develop or are born with lactose intolerance which is anon-allergic food sensitivity, and comes from a lack of production ofthe enzyme lactase, required to digest the predominant sugar in milk.Adverse effects of lactose intolerance generally occur after much higherlevels of milk consumption than do adverse effects of milk allergy. Milkprotein intolerance (MPI) is delayed reaction to a food protein that isnormally harmless to the non-allergic, non-intolerant individual. Milkprotein intolerance produces a non-IgE antibody and is not detected byallergy blood tests. Milk protein intolerance produces a range ofsymptoms very similar to milk allergy symptoms, but can also includeblood and/or mucus in the stool. Treatment for milk protein intoleranceis the same as for milk allergy. Milk protein intolerance is alsoreferred to as milk soy protein intolerance (MSPI).

For formula fed infants, milk substitute formulas are used to provide acomplete source of nutrition. Milk substitutes include soy basedformulas; hypoallergenic formulas based on partially or extensivelyhydrolyzed protein, and free amino acid-based formulas.

Non-milk derived amino acid-based formulas, known as amino acid formulasor elemental formulas, are considered the gold standard in the treatmentof cows milk allergy when the mother is unable to breastfeed.

Hydrolyzed formulas come in partially hydrolyzed and extensivelyhydrolyzed varieties. Partially hydrolyzed formulas (PHFs) arecharacterized by a larger proportion of long chain peptides and areconsidered more palatable. However, they are intended for milder casesand are not considered suitable for treatment of moderate to severe milkallergy or intolerance. Extensively hydrolyzed formulas (EHFs) arecomposed of proteins that have been largely broken down into free aminoacids and short peptides. Casein and whey are the most commonly usedsources of protein in hydrolyzed formulas because of their highnutritional quality and their amino acid composition.

Soy based formula may or may not pose a risk of allergic sensitivity, assome infants who are allergic to milk may also be allergic to soy. Alsosoy based formulas are not recommended for infants under 6 months.

Infant formulas also come in a variety of types:

Cow's milk formula is the most commonly used type (e.g.: Similac,Enfamil).

Soy protein based formulas are frequently used for infants allergic tocow's milk (e.g.: Isomil, ProSobee).

Partially hydrolyzed formulas (e.g.: Good Start and Gentlease brands)are marketed as having improved digestibility.

Extensively hydrolyzed formulas (e.g.: Alimentum, Nutramigen, andPregestimil) are considered “hypoallergenic”. One study reported that90% of children with cow's milk allergies will tolerate them.

Amino acid based formulas (e.g.: Neocate, EleCare, and Nutramigen AA)are more expensive, but are reported least likely to cause allergicreactions.

Hypoallergenic formulas, such as those containing free individual aminoacids, and sometimes referred to as elemental infant formula, areconsidered to reduce the likelihood of certain medical complications inbabies with specific health problems, such as severe allergies to cow'smilk and soy. Made of purely synthetic monomeric amino acids, they areoften considered quite foul-tasting, and it is not uncommon for infantsto reject elemental formulas after having been established on asweeter-tasting regular formula, thus the level of compliance of infantsin an age wherein feeding is crucial, such incompliance is lifethreatening.

SPIFs (Soy Protein Infant Formulae) contain phytoestrogens, mostlyisoflavonoids (particularly diadzein, genistein). It was shown thatthese substances tend to bind to estrogen receptors and behave as pro-or anti-estrogens. The amount of phytoestrogens in SPIF (32-47 mg/liter)is 40 times higher than the amount in breast milk. Consumption ofisoflavonoids from SPIF reaches 11 mg/kg body weight per day, and theirlevels in infant blood were 13,000 to 22,000 times higher than the bloodlevels of estrogen-like substances in the first years of life. Infantswho are fed only on SPIF are exposed to a daily consumption ofisoflavonoids that is 4-13 times the amount presumed to have aphysiological effect on balancing the menstrual cycle in women. Recentlythe scientific literature has raised some concerns regarding the vastconsumption of SPIFs regarding the fact that phytoestrogens could havean adverse effect on infant and child growth (they are not recommendedfor premature infants weighing less than 1800 grams), development andpuberty, bone health and thyroid function. In addition, the fact thatmost of the soy crops are genetically engineered the use of SPIF is notrecommended in certain countries and is regulated to the extent ofrequiring a prescription for administration for infants having severeallergies.

There is therefore a true need in the art for a non-dairy formula forinfants that can provide all essential nutritional needs similar to thegold standard of breast milk nutritional profile without thedisadvantages of currently known non-dairy formula.

Example 1

I. Almond Component

-   -   a. Almonds are pasteurized during drying in two steps: (a) in        the slurry before the drum dryer. (72 C, 40 sec) and (b) on the        drum dryer as part of the pre gelatinized.    -   b. Reduction of the phytic acid content is performed by        marinating and washing the almond component or by using phytase        enzyme (process is controlled by heating the slurry to        inactivate the phytase enzyme).    -   c. Bleaching the almond component.

II. Buckwheat Component

-   -   a. The buckwheat should be pre gelatinized in order to be        available for babies' consumption. The pre gelatinized process        causes a high viscosity when the powder is mixed with water.    -   b. The buckwheat can be hydrolyzed with enzymes (such as for        example Amylase) in order to reduce its viscosity. The        hydrolization process gives an ability to control fiber content        to the levels required.    -   c. The hydrolyzed process is taken place when the buckwheat is        dissolved with water before drum drying.    -   d. Amylase is added to the solution at 30-37 C.    -   e. The enzyme is inactivated by raising the temperature to above        50 C.

III. Production Process

-   -   a. The Buckwheat is mixed in water.    -   b. Heat the slurry to 37 C.    -   c. Add and mix the enzymes.    -   d. The slurry heated up to 55 C in order to inactivated the        enzymes activity    -   e. Add to the hydrolizated buckwheat and mix all other        ingredients, that are: almonds, minerals, vitamins.    -   f. Feed the slurry to the drum dryer.    -   g. Drying conditions    -   h. Dry mixing stage: with reactive metals Zn, Cu, Mg.
